For performance testing we will first test idle temperatures. These are taken on the Windows 10 desktop an hour after the system has been turned on.

For load testing we will be running the AIDA64 system stability test with the CPU only checked. This puts a full load on our CPU. We run this test for 1 hour and record the highest temperature throughout the test.

As mentioned previously, the LS720 WH features two ARGB LED lighting zones in the pump housing, as well as three FC120 fans with ARGB lighting. The included 3-pin ARGB connectivity of this AIO allows you to connect these devices to a compatible motherboard or run the unit in a standard rainbow effect mode when not connected. Unfortunately, the motherboard used in our testing rig does not support 3-pin ARGB lighting, so we were only able to test with the default rainbow effect. That said, the lighting did look quite nice, and I really liked the pastel-like colors that the fans gave off. Below are a few shots of the cooler running with the rainbow effect.
